The southern hemisphere of Saturn's moon Rhea is seen in this polar stereographic map, mosaicked from the best-available images obtained by NASA's Cassini spacecraft.
This map is an update to the version released in February 2010 (see Rhea Polar Maps - February 2010). The title of the older version ("Rhea Polar Maps - February 2010") denotes the month the map was released, not when the data in the maps were collected. The title of this new version reflects when the most recent data used in the map were captured.
The map is centered on the south pole, and surface coverage extends to the equator. Grid lines show latitude and longitude in 30-degree increments. The scale in the full-size versions of these maps is 417 meters (1,400 feet) per pixel. The mean radius of Rhea used for projection of these maps is 764.1 kilometers (474.8 miles).
The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate in Washington. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging team is based at the Space Science Institute, Boulder, Colo.
